Bauxite deposits are spread worldwide mostly occurring in tropical or subtropical regions 8 Bauxite mining of both metallurgical and nonmetallurgical grade ores is analogous to the mining of other industrial minerals Normally the beneficiation or treatment of bauxite is limited to crushing sieving washing and drying of the crude ore 3 The bauxite ore Bayer process materials before precipitation mud residue and sand residue are therefore of radiological interest whereas the alumina product is not 8 Positional and personal monitoring data from bauxite mines and alumina refineries in Western Australia have been used to assess the abovebackground annual doses for the

Bauxite is a heterogeneous naturally occurring material of varying composition that is relatively rich in aluminium The principal minerals in bauxite are gibbsite Al 2 O 3 3H 2 O boehmite Al 2 O 3 H 2 O and diaspore which has the same composition as boehmite but is denser and harder Australia is the worlds largest producer of Bauxite is not a mineral but rather a group of aluminum oxides The term is generally used to describe the economically important mixture of these minerals which form a mass of the individually classified members of Gibbsite Boehmite and DiasporeBauxite does not make aesthetic or interesting specimens as far as collectors are concerned but it holds importance as being the primary ore of
